' SPECIFICATION forming part of Letters Patent No. 748,154,datedDecember 29, 1903.

Application filed June 4, 1903. Serial No. 159,988. (No model.)

To all whom it may concern.-

Be it known that I, JAMES R. BARRY, of Syracuse, in the county ofOnondaga, in the State of New York, have invented new and usefulImprovements in Tops, of which the following, taken in connection withthe ac companying drawings, is a full, clear, and exact description.

This invention relates to improvements in tops, and refers particularlyto that class which is adapted to be spun by a cord.

The primary object is to prevent the slipping or displacement of thecord during the operation of winding and to permit the cord to readilydetach from the top when unwound in the act of spinning.

Further objects will appear in the subsequent description.

upper face to receive a detachable plug or shoulder 4. This recess ispreferably circular, and its inner end is reduced in diameter to form anannular horizontal shoulder or seat 5, which serves to limit the inwardmovement of the plug, while the vertical side walls of the outer orlarger end of the recess serve to prevent lateral displacement of saidplug. The plug is formed with a central aperture, through which the cord2 is inserted, the innor end of said cord being tied into a knot 6,which projects into the reduced inner end of the recess, so as not tointerfere with the insertion of the plug and whereby the plug isdetached from the top when the cordisunwound in the act of spinning saidtop. It is thus seen that the top and operating-cord are formed withinterlocking shoulders, whereby one end of the cord is held while theremain ingportion is wound in the usual manner around the periphery ofthe top preparatory to spinning the same, the attachment of said endserving to prevent slipping of the cord while being wound upon the top.

In spinning the top it is thrown or tossed in the usual manner to unwindthe cord therefrom, and .as soon as this unwinding is effected thesudden termination operates to draw the plug from its seat, and the toptherefore continues to spin unimpeded, and the plug is held upon thestring or cord by the knot 6, to be again inserted in the recess 3 torepeat the operation.

The peg or spur upon which the top rests when spinning is here shown asconsisting of a ring or eye 7, which is disposed vertically to form acurved bearing-face and is formed with a stud 8, projecting into anopening in the lower or apex of the top and secured thereto.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is

A top having a recessed upper face, said recess being enlarged at theupper portion thereof to form a shoulder, a plug, said enlarged portionof the recess being of the same height as the thickness of said plug, acord attached to the plug with a knot formed on the cord to extend insaid recess.

In witness whereof I have hereunto set my hand this 28th day of May,1903.

JAMES R. BARRY.
